| 摘 要： | 针对平衡与非平衡输入电压对空间矢量调制的矩阵变换器进行了仿真分析。第一种情况下验证了矩阵变换器的优良特性及空间矢量调制原理的可行性;也发现即使三相输入电压平衡,输入电流也存在失真现象。第二种情况与前者形成鲜明的对比,反映了非平衡输入电压对矩阵变换器输入、输出性能的巨大影响。提出了在输入、输出端设计滤波器以减轻或消除谐波的观点。 |

| Abstract: | The simulated study on a matrix converter(MC) is carried out based on space vector modulation (SVM) under balanced and unbalanced input voltages. The excellent properties of a matrix converter and validity of space vector modulation for a matrix converter are verified under the first thing. It is found that the input current produces distortion even if the three-phase input voltages are balanced. Compared with the first thing, the second one reflects that the unbalanced input voltage has great effects on input and output properties of a matrix converter under the unbalanced input voltage. A viewpoint is put forward that filters should be designed to reduce or eliminate harmonics at the input and output ports. |
| Keywords: | matrix converter space vector modulation balance unbalance input voltage simulation |
